Magma; they are both the same substance, but lava has been exposed to the surface.
When a substance goes from a solid to a liquid, it is melting. Generally, it is easier to heat an object that has more surface area because it has more area being exposed to heat.
An open pit mine, or quarry, is exposed on the surface.
-- the area of the exposed surface -- the airflow over the exposed surface -- the temperature of the liter of water -- the air pressure at the exposed surface -- the relative humidity of the air in the room -- the transparency of the liter container are all relevant to the rate of evaporation.
When the exposed surface of water is larger the evaporation is faster.

The larger the exposed surface area - the faster evaporation occurs.
The SA mentioned here refers to Surface Area, or how much surface the substance will cover
A greater surface area means a greater portion of the solid(solute) is in contact with the solvent at a given time. This increases the area in which interaction between the 2 substances can take place, and thus the rate at which the solute dissolves.
When the exposed surface of water is larger the evaporation is faster.
If you clean with a cleaning substance and use appropriate cloths and rags your much more likely to have a cleaner surface. It also depends on the type of surface that is being cleaned. For example your more likely to be successful with a cleaning substance on linoleum than water.
What procedure to follow if exposed skin comes in contact with any chemical substance
It is the amount of surface of a solute that is exposed to the solvent. The smaller the pieces of the solute are, the larger the surface area that is exposed to the solvent.
Burning is a chemical process - oxidation - that usually takes place where oxygen from the air reacts with the substance that is burning. The surface area determines how much oxygen is in contact with the substance.
